IMPROVEMENT lN WINDMILLS.

kSpecification forming part of Letters Patent No. ,527,951 dated April 1T, 1860.

Similar letters of reference indicate corre-` spending,r parts in the several figures.

This invention relates to an improvement in that class ot wind-wheels which are commonly termed portable, and which are more' especially designed for driving light machinery.

The object of the within-described invention is to simplify and economize in the construction of such class of windfwheels, and at the same time render the same morel efficient y than hitherto.

The invention consists in the employment or use of a deflecting-cone placed over the gearing` and'so arranged relatively with the wheel that it may serve as a vane and -keep the former facing the wind, the cone serving the triple purpose of vane, cover, or protector to the gearing and deflectorto cause the wind 'to act in the most efficient manner against the wind-wheel.

freely thereon, a vertical shaft D serving as' a center for the cap. The shaft D passes through the cap C and block B and is allowed to turn freely in both. The upper ends ot the shaft D has a pinion E on it, and this pinion gears into al corresponding' pinion F on a hollow shaft G, which is fitted in. proper bearings on cap C. Toone end of the hollow shaft G the wind-wheel ll is attached. This wheel is formed ot a series of sails or wings u., attached to adial arms l), the inner ends of which are .fitted inv the shaft G, and the outer ends fitted .in a ring or band c. The arms l) are allowed to turn freely in their bearings, and to each sail or wing a a cord or rope dis attached at the lower end of the side opposite to that where the sail or wing is attached to its arm b. The cords or ropes of the several sails or wings are all connected within the hollow shaft G to a common cord or rope I, and this rope is connected by a swivel@ to a rope J, which passes through a guide e and has a weight K attached toits lower end. Thev weight K is the exponent ofthe power of the wheel, for in consequence ot being connected to the sails or wings, as described, the latter are render-ed self-regulating and are allowed to yieldor give in accordance with the gravity of the `weight. This self-regulating meehanism, however, isquite common and well known, and therefore does not require a minute description. n

L is a hollow cone, which may be constructed of wood or metal. This cone has a section- 'removed or cut out from one side, so that it may be fitted horizontally. over the gearingE Fand on the cap C, the larger end of the cone being' next the wheel, as shown clearly in Fig. 2. The point ot the cone projects some distance beyond the'cap C.

The cone L, it willbe seen, serves asa covering or protector for the gearing E F, audit also serves to deflect the wind toward the outer part of the wheel, as indicated by the arms in Fig. 2, rendering the wind-wheel more elheient than it otherwise would be. The cone also for the above reason serves further to render the turnineot thewheel quicker with thel changes of lthe wind.

Ido not claim the turning sails-or wings a with a weightconnected to them to render the wheel self-regulating, forsuch device has-been previously used; but

I do claim as new and desire to secure by Letters Patent--- The employment or use oli' the cone L, applied to the revolving cap C and placed relatively with the wind-wheel ll and gearing E l?, to operate as and tor the purpose set forth.
